Note - I would not use var and I don’t think the course encourages it at all

In this video/transcript that talks about using let or const to declare variables, it says:

You can also use the var keyword, but it’s not as recommended anymore. The var is kind of like let , except it has a wider scope, which is more likely to cause problems in your program.
